mustafagander,
I edited the post for clarity.
The arguement that the relief pilot is off duty for calculation of limitations is the point in question. Considering an S/O off duty whilst sitting working on the flight deck simply as he does not occupy the control seat clouds the logic of duty associated with employment. This is where the CAO is clear. To now state that the pilot is perform statuatory duties in the cabin removes any doubt as to the not on duty (hence resting) arguement..
I also have issues with the certified agreement being amended, unilaterally. AGAIN
